T w'lwm it m y 66 7 vations of modified forms of my invention, Be itknown that I, CHARLES BUSH, a citiand Figs. 6, 7, and 8 inverted plansof the zen of the United States, residing at Newsaid modified forms.burgh, in the county of Orange and State of With reference to Figs. 1and 2, (1 indicates New York, have invented 'an Improvement asupporting-bar, the same preferably reprein Spring-Supports forUpholstery, of which senting a member of a frame of an article of thefollowing is a specification. furniture, which, as an illustration,might be My invention relates to spring-supports for part of aseat-frame, part of a sofa-frame, or upholstery, and particularly tosprings of inpart of the frame of a spring-bed. b reprero verted conicalor spiral form connected to sentssupporting-wires, and c crossing wires,and supported upon a wire or crossing wires; which crossing wires may ormay not also be and the object of my invention is to securelysupporting-wires. The supporting-wires are fasten and lock' the base ofthe springs to preferably formed in accordance with the such part orparts, so that there will be no structure shown and described in Letters15 slipping or shifting of the one with reference Patent granted to JohnA.

(1represents a clip or 25 ing-wire or between the diameters of thekey-block comprisinga plate of metal of subcrossing wires, the said clipor key-block bestantially the thickness of the wire of the ing of adiameter substantially agreeing with spring h, which spring is ofinverted conical the inner diameter of the smaller convoluor spiralform. This clip or key-block dis tions of the spring, having thefunctional preferably provided upon opposite sides and 0 efiect ofcentering the spring upon its supextending in opposite directions withcentral port. The structure to which I give preferintegral lugs 4: 5,and said block d is of a dience comprises a clip or key-block in theform ameter agreeing substantially with the inner of a plate of metal ofsubstantially the thickdiameter of the smaller convolutions of said nessof the Wire of the inverted spiral spring spring h, the plate, as shown,having four 35 and crossing wires, one or both of which form equidistantextensions or arms. As shown supports, said clip or keyblock agreeingsubin Figs. 1 and 2, the supporting-wire b lies stantially in diameterwith the inner diameagainst the under surface of the block d and ter ofthe smaller convolution, and said conthe crossing wire against the uppersurface, volution occupying a position between the the lug 4 being bentinto gripping contact 40 diameters of the crossing Wiresthat is to withthe wire I) and the lug 5 over the wire 0 say, occupying a positionabove one wire and to hold said wires firmly to said clip or keybeneaththe otherthis clip or key-block beblock. In this structure the coil ofthe ing provided with integral lugs bent over springthat is, the smallerand lower conupon the crossing wires, which lie against volutionisscrewed about the clip or key- 5 opposite faces thereof and in oppositedirecblock and between the diameters of the cross- 5 tions. ing wires,thus locking the base of the spring In the drawings, Figure 1 is anelevation firmlyin place to the crossing wires and conand partialsection representing the preferred tering the same in position by thesaid clip form of my invention. Fig.2 is an inverted or key-block lyingwithin the convolution. 50 plan of the same. Figs. 3, 4:, and 5 are ele-In this structure the spring cannot slip in either direction, nor canthe wires move with reference to one another, and the base of the springis so firmly held and centered that the usual tying-cords are almostunnecessary.

In the structure shown in Figs. 3 and 6 the clip or key-block e is inthe form of a cylindrical section, with transverse holes at right anglesto one another and separated in horizontal planes by substantially thediameter of the wire of the spring, the diameter of the clip orkey-block agreeing substantially with the inner diameter of the smallerconvolution of the spring, and in this modified form the coil of thespring is screwed around the block 6, with the parts of the convolutionscoming above and beneath, or, in other words, between the respectivecrossing wires, the convolution being put under tension in saidstructure, so as to form a frictional grip on the crossing wires, whichfrictional grip is also manifest in the structures shown in Figs. 1 and2.

In the modified form of my invention shown in Figs. 4 and 7 frepresentsa clip or keyplate of sheet metal of yoke shape which in length agreessubstantially with the inner diameter of the smaller convolution of thespring, one crossing wire passing through within the bent portion of theplate and the other wire at right angles thereto passing through holesin said plate and the Wires separated in their horizontal planes adistance substantially agreeing with the diameter of the wire of thespring and the convolution passing beneath the one and above the other,tension being applied in the act of connecting the parts to form africtional hold, as hereinbefore stated.

In the modified form of the invention shown in Figs. 5 and 8 the springis connected to and supported upon a single flattened wire, the clip orkey-block being of the form of an X- plate or crossing arms withchannels in opposite faces, one channel being centraland receiving thesupportingwire 19' and the channels in the opposite face being in lugsat the respective ends and receiving the wire at opposite sides of theconvolutions. In this instance the coil of wire is screwed around theblock 8, and a frictional tension is applied not only to forcefully holdthe spring to the block but the wire to the block, the convolutionspassing under the block and over the wire.

I claim as my invention- 1. In spring-supports for upholstery, thecombination with the inverted conical or spiral springsand asupporting-Wire, of a clip or key-block device extending along acrossand engaging the supporting-wire and coming substantially within theplane and limits of the lower convolution of the spring and with whichdevice and the supporting-wire the lower convolution of the spring isbrought into forceful frictional contact under tension so as to lock therespective parts in a fixed position, substantially as set forth.

2. In springsupports for upholstery, the combination with the invertedconical. or spiral springs and a supporting-wire, of a clip or key-blockdevice adapted to be connected to the supporting-wire and in diameteragreeing substantially with the inner diameter of the smallerconvolution of the spring and received within the limits of theconvolution and with which device and wire the lower convolution of thespring is brought into forceful frictional relation under tension bypassing over the one and under the other, substantially as specified.

3. In spring-supports for upholstery, the combination with the invertedconical or spiral springs, and a supporting-wire, of a crossing wire atright anglesto the supporting-wire and separated in a horizontal planeat a distance substantially agreeing with the diameter of the wire ofthe spring, a device contacting with and engaging the respectivecrossing wires, occupying a position within the smaller convolution ofthe spring, and of a diameter substantially agreeing with the innerdiameter of the smaller convolution of the spring,and which device saidconvolution surrounds and is brought into forceful and frictionalcontact with and between the supporting and crossing wires to hold thesaid parts in a fixed relation, substantially as specified.

4. In spring-supports for upholstery, the combination with the invertedconical or spiral springs, and a supporting-wire, of a crossing Wire atright angles to the supporting-wire, a clip or key-block occupying aposition between said crossing wires and against the surfaces of whichsaid wires contact, means for holding the said wires firmly to saidblock, said block being of a diameter substantially agreeing with theinner diameter of the smaller convolution of the spring, and of athickness substantially agreeing with the thickness of the Wire of thespring and with which block and crossing wires the said convolution isconnected by screwing the same around said block and between thediameters of the crossing wires, substantially as set forth.

5. In spring-supports for upholstery, the combination with springs ofinverted conical or spiral form, of supporting and crossing wires atright angles to one another, clip-or key-blocks each comprising a plateof metal of substantially the thickness of the wire of the spring and ofa diameter substantially agreeing with the inner diameter of the smallerconvolutions of the spring, lugs formed centrally and upon oppositesurfaces of said clip or key-block and adapted to be,

bent over the respective supporting and crossing wires lying against theopposite surfaces of said block to hold said wires in a fixed re lationto said block, the spring being secured by turning the lower convolutions around said blockand between the upper and lower surfaces of therespective crossing wires, and in so doing compressing and putting undertension the lower convolution to forcefully and frictionally hold thebase of the spring to the crossing wires and centering the same by meansof said block,substantially as set forth.

6. In spring-supports for upholstery, the combination with the invertedconical or spiral springs and asupporting-wire, of a crossing wire atright angles to the supportingwire, a clip or keyblock occupying aposition between said crossing wires and engaging the same and withwhich block and the crossing wires the smaller convolution of the springis connected by screwing the same around the said block and between thediameters of the crossing wires, substantially as specified.
